LUBRICA'I'OR.

Application filed. September 18, 1925. Serial No. 57,151.

My invention is in a lubricator adapted for loconotives and comprisesforced feed the locomotive.

An object of my invention is to provide reservors for Oll having steamoperated pistons for forcing the'oil from the reservoirs to lubricatingappliances such as the,

flange oiler device and cylinder lubricating devices which are standardon locomotives.

In my invention I utilize a container having a pair of cylinders Withpistons therein, each of the cylinders having a different type `oflubricatng oil and having pistons mounted in the cylinders with a steamconnection whereby steam may be forced into the cylinders and force theoil outwardly; such oil being led by pipes to lubricating devices whichare so designed that they can only hold a limited amount of oil.

Another feature of my invention is in passing the stean through thecontainer to maintain the oil at proper temperature and fluidity withmanually controlled valves positioned in a base plate of the containerto govern the flow of steam.

Various other features of my' invention pertain to the details ofconstruction of the container and oil cylinders.

My invention will be more readily understood from the followingdescription and drawings, in which;

Figur-e l is an elevation of my oil reservoir container, indicating asystem of steam piping leading thereto and a system of oil pipes leadingtherefrom to locomotive oiling appliances.

Fig. 2 is a. side view of Fig. 1 in the di-' rection of the arrow 2.

Fig. 3 is a top view of my reservoir con tainer taken in the directionof the arrow 3 of Fig. 1.

Fig. t is a vertical longitudinal section of my reservoir containertaken on the line lt of Fig. 3 in the direction of the arroWs, showingthe oil cylinders.

Fi 5 is a horizontal cross section of F ig. e on the line 5-5 in thedirection of th arrows.

Fig. 6 is a horizontal section of Fig. 4 on the line 6-6 in thedirection of the arrows, indicating the oil cylinders.

Referring particularly to Figs. l and 2, my oil reservoir container isindicated generally by the numeral l; a standard fiange oiling device isdesignated by the numeral 2; a'cylinder valve lubricator by the numeral3; a stean supply donie is designated by the numer-al' e, connected tothe boiler 5. As the fiange oiler 2 and the valve cylnder lubricator 3,together with the steani dome do not form a definite feature of myinvention, they will not be more fully described.

My oil reservoir container l is preferably for-med of a relatively largecast body 10 having a pair of oil cylinders ll and 12 formed at thelower end; these cylinders have an open base closed by a cover plate 13secured by bolts ll to the metal structure of the cylinders. An oilreservoir 15 is constructed in the upper part of the containerpreferably by coring in the casting operation and is closed by a fillerplug 16 and has an outlet tap 17 through which oil may be drawn to fillthe oil cans utilized by the engine crew.

The steam Operating features of my oil reservoir comprises a'piston 20in each of the cylinders ll and 12 each having a piston rod 21 extendingupwardly into spring boxes 22, the latter being formed by coring thecasting and the piston rods having heads 23. Compression springs 24 arehoused in the spring boxes and are under compression between the pistonrod heads 23 and the screw threaded plugs 25 closing the upper ends ofthe spring boxes.

Steam is fed under the pressure to the oil cylinders beneath the pistonsby means of inlet oil pipes having valves 31 ducts 32 extendingdownwardly through the casting of the container and horizontalconnections 33 leading into the steam chamber The stean has a passage 35through the casting at the rim of the cylinders through an aperture 36in the cover plate 13 and enters a T 37. This T leads to branch pipes38, having globe valves 39, the latter having nipples 40 leading throughthe cover plate 13 to the lower side of each of the pistons 20. Draincocks il are lil ewise provided in the cover plate 13 to allow drainageof the water condensed froni the steam. A stean blow ofi outlet isprovided by a horizontal duet 42 from the steam chamber 34 to thevertical duct 43 which latter leads to a blow ofi pipe 44: controlled bythe valve 45.

The oil is charged into the oil cylinders through similar plugs mountedin the reservoir casing above the cylinders and is fiange oiler 2and-thepipe 52 to the cylinder 5 valve lubricator 3.

A pair of sight holes 54 are provided- With glass covers so that a,person may ascertain i' the oil cylinders contain oil.

The manner of .operation ofniy lubrica- 1 tor container is substantiallyas toiiows: 'It Wilibe understood :that before beginning a run on alocomotive that the reservoir `ivill be filled With oii through theplug` 16 and that the oil cylinders ll and 12 will be 15 filied'throughthe plugs 50, With the pistons "20 in their bottom position restingonthe cover plate lQ. As the oil inthe fiange oler` 2 and the vaiveoilerS are used up the valve 39 may be opened to feed 'stean fromthestea1nchamber84-to the base of either of the cylinders ll and l2,itbeing understood thatthe steani valve Bl Will normally be opened toallow stean to enter the `stearn chaniber -and to maintain the 'on atproper temperature.

My invention may 'be considerabiy changed in general Construction andindetail to suit it for--supplying oil to different ,types of lubricating appiiances, such changes being within the scope of iny in-'vention as expressedin the 'clains Having descrbed iny invention, WhatI claim is:

l.A '1ubricator reservoir coniprising 'an' integral bodystructure havinga pluraiity oioil cylinders *Jorined therein, a cover piate for the-baseof the cylinders, pistons in the cyinders, ineans to fill the cylindersWith oil, a stoan' chanber in the body structure adjacentthecylinders,*1neans 'or conducting steain through the body structuretoandfron the steani chanber, and means for conductiiig steam 'from thesteam chamber through the cover piate to' the base of the pistons.

52. A lubrcator rescrvoir -as 'claimed in ciain 1, having in addition apiurality of :bores in the body` structure above t he cyiinders formingspring boxes,piston rods conrod extending' through the' opening in thecored section, the piston rod havlng a head thereon, a spring in thec'ored section bearng against the'pston rod'headend said plug, means' tointroduce oil into the 'cylinder, apipe leading through the cover plateto"flow 'steain into the c'yiinder below the piston, a pipe leading'froni the upper portion of the cylinder to a lubricating device, a steamchan'ber in the body structure adjacent the cyiinder and steain'ductsthrough the body structure- ;leading to the stea'in chainberand astean' pip connected'to the stean 'chanber through the cover piate andto the pipe leading into the cylinder.

4. A' lubric'ator reservoir c omprising a container fol-med of a bodystructure having a reservor inits upper portion and a pair of oilcylinders in itslower portion, a cover plate closing the cylinders, apiston in each of the cylinders, means to introduce oil into thereservoir and thecylin ders, pipes conductng steam through' 'the coverpiate into the c ylinders below the pistons,`pipes to discharge oil'froni'the cylinders to' lubricating devices, an outlet tap for oil ironithe reservoir, a'stean chanber in the'iower portion of the bodystructure between the cylinders, and duots conveying steam through thebody structure to' the steain charnber and ironi the steain chaniber tothe pipes leading through the cover piate.

In testimony Whereof I have signed my name to this specicaton.
